  • Take a look at this:-


    Code Snippet
      <script type="text/javascript">
    function chk_onchange()
     var ctl = document.getElementById(this.getAttribute("enableWhenFalse"))
     ctl.disabled = this.checked
      <span>Like Apples?</span>
      <input type="checkbox" enableWhenFalse="txtApples"
        onchange="chk_onchange.call(this)"  />
      <br />
      <input id="txtApples" type="text" />



    Note that the chk_onchange function can be re-used for any checkbox that you want this behaviour for.  You just need to add the enableWhenFalse attribute to point to the control you want to disable when the check box is checked.
